Проанализировать результаты тест-систем «ГастроПанель» и «ГастроСкрин-3» за 15 лет наблюдения и определить частоту аутоиммунного гастрита (АИГ) в клинической практике и в случайной выборке жителей г. Новосибирска. Материалы и методы. Показатели биомаркеров были проанализированы в двух группах: 1 742 человека, средний возраст 50,0 ± 13,53 лет (тест-система «ГастроПанель», компания «Биохит», Финляндия), и 170 человек, средний возраст 53,8 ± 12,89 лет (тест-система «ГастроСкрин-3», АО «Вектор-Бест», Россия), с 2007 по 2022 г. Расчет частоты АИГ проводился в текущей клинической практике и в случайной выборке жителей г. Новосибирска 45–69 лет. Верхней границей нормы считали показатель пепсиноген I (ПГI) – 160 мкг/л, умеренной атрофии соответствовал диапазон ПГI 31–50 мкг/л, а ПГI ≤ 30 мкг/л и соотношения ПГI/ПГII ≤ 3 – выраженной фундальной атрофии. Аутоиммунный гастрит рассматривали при показателях ПГI ≤ 10,1 мкг/л, ПГI/ПГI ≤ 1,3; гастрина-17 ≥ 42,4 пмоль/л («ГастроПанель») и ПГI ≤ 16,8 мкг/л, ПГI/ПГII ≤ 1,5 тест-система («ГастроСкрин-3», АО «Вектор-Бест», Россия). Положительным считали уровень иммуноглобулина класса (Ig) G H. рylori более 42 EIU. Антитела к CagA-белку определяли с помощью тест-системы «Хелико-Бест антитела» (АО «Вектор-Бест», г. Новосибирск).Результаты. Серологические признаки выраженной и умеренной фундальной атрофии выявлены: 10 и 9,4% («ГастроПанель»), 13,3 и 7% («ГастроСкрин-3») соответственно. Признаки мультифокальной атрофии обнаружены в 0,7%. Иммуноглобулины класса G H. pylori определялись в 57,7%, CagA+ штамм – в 56,1% случаев. Язвенный фенотип гастрита был обнаружен у 15,3% («ГастроПанель») и у 10% («ГастроСкрин-3»). Частота АИГ по данным тест-систем «ГастроПанель» и «ГастроСкрин-3» в случайной выборке составила 1,6%, в текущей клинической практике – 2,6 и 3,5% соответственно. Заключение. В группу риска развития рака желудка попали 20% обследованных, у 10–15% обнаружен язвенный фенотип, что требует дообследования. Частота АИГ в исследуемых группах на основании серологического скрининга составила 1,6–3,5%. </p></abstract><trans-abstract xml:lang="en"><p>Aim. To analyze the results of the GastroPanel and GastroScreen-3 tests over a 15-year follow-up and determine the incidence of autoimmune gastritis (AIG) in clinical practice and in a random sample of Novosibirsk residents. Materials and methods. Biomarkers were analyzed in two groups: 1,742 people, average age of 50.0 ± 13.53 years (GastroPanel test, Biohit Oy, Finland), and 170 people, average age of 53.8 ± 12.89 years (GastroScreen-3 test, Vector-Best, Russia), from 2007 to 2022. The AIG incidence was calculated in current clinical practice and in a random sample of Novosibirsk residents aged 45–69 years. The PGI level of 160 µg / l was taken as the upper limit of normal, PGI of 31–50 µg / l indicated moderate atrophy, PGI &lt; 30 µg / l and the PGI / PGII ratio ≤ 3 indicated severe gastric fundus atrophy. AIG was considered at PGI ≤ 10.1 μg / l, the PGI / PGI ratio ≤ 1.3, and gastrin-17 ≥ 42.4 pmol / l (GastroPanel) and at PGI ≤ 16.8 μg / l and the PGI / PGII ratio ≤ 1.5 (GastroScreen-3). The H. pylori IgG level &gt; 42 EIU was considered to be positive. Antibodies to CagA protein were determined using the HelicoBest Antibody test (Vector-Best, Novosibirsk). Results. Serological signs of severe and moderate gastric fundus atrophy were detected in 10 and 9.4% (GastroPanel test) and in 13.3 and 7% (GastroScreen-3 test) of those examined, respectively. Signs of multifocal atrophy were found in 0.7% of cases. Antibodies to H. pylori were detected in 57.7%, CagA+ strain – in 56.1% of cases. Peptic ulcer disease (PGI ≥160 µg / l) was found in 15.3% (GastroPanel test) and 10% (GastroScreen-3 test) of the examined. According to the GastroPanel and GastroScreen-3 tests, the incidence of AIG was 1.6% in a random sample and 2.6 and 3.5% in current clinical practice, respectively. Conclusion. Twenty percent of the examined persons were at risk of developing gastric cancer and 10–15% had peptic ulcer disease, which requires further examination. The incidence of AIG in different study groups based on serological screening was 1.6–3.5%. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>пепсиногены</kwd><kwd>«ГастроПанель»</kwd><kwd>«ГастроСкрин-3»</kwd><kwd>Helicobacter pylori</kwd><kwd>фундальная атрофия</kwd><kwd>аутоиммунный гастрит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pepsinogens</kwd><kwd>GastroPanel</kwd><kwd>GastroScreen-3</kwd><kwd>Helicobacter pylori</kwd><kwd>fundus atrophy</kwd><kwd>autoimmune gastritis</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена по государственному заданию в рамках бюджетных тем «Изучение молекулярно-генетических и молекулярно-биологических механизмов развития распространенных терапевтических заболеваний в Сибири для совершенствования подходов к их ранней диагностике и профилактике», 2024–2028 гг.
